What is WEP, WPA, WPA2? What is the best wifi security standard?

WEP, WPA, WPA2 are common wifi security standards. But do you really know about these security standards? Among them, which is the best wifi security standard? Let’s find out more with lassho.edu.vn in the article below!

What is WEP, WPA, WPA2, WPA3?

What is WEP?

WEP (Wired Equivalent Privacy) is the oldest wifi security standard, born in 1997. This is considered the least secure wifi security method. In 2004, the WEP security standard was dropped .

What is WPA?

WPA (Wi-Fi Protected Access) is a security standard developed to replace WEP because WEP encryption is outdated and easily broken.

WPA has many improvements over WEP such as supporting TKIP (Temporal Key Integrity Protocol) to prevent the theft of packets transmitted in wifi and MIC (Message Integrity Check) to ensure data is not tampered with. However, WAP still has some vulnerabilities from WEP.

What is WPA2?

WPA2 has been the replacement security standard for WPA since 2006. WPA2 also replaced TKIP with the CCMP (Counter Mode Cipher Block Chaining Message Authentication Code Protocol) protocol .

CCMP is a unified data transfer and data transmission control protocol that ensures both the confidentiality and integrity of transmitted data. Currently, most wifi routers use WPA2.

What is WPA3?

WPA3 is the latest wifi security standard today and is applied on some routers manufactured in 2019. WPA3 is upgraded to be more optimized than the WPA2 security standard.

WPA3 provides security on public wifi networks , preventing hackers from being able to see or steal information when you connect to public wifi such as at airports, restaurants, …

With the WPA3 security standard, it is difficult for hackers to guess your wifi password , and at the same time prevent hackers from deciphering traffic even if they already know the wifi password.

Why is wifi security important?

Wifi security helps you prevent strangers from taking up Internet bandwidth , restricting strangers from entering your wifi , and wifi security also helps to ensure the safety of your data.

Knowing your wifi security standard is an extremely necessary job. This will help you understand how secure the wifi security standard you are using is.

Older security protocols are often more vulnerable to attacks than new ones. So when you know the wifi standard, you can take measures to increase the security of wifi.

How to check which security standard you are using?

Step 2: Click Properties below the wifi name you are connecting to.

Step 3: Check the wifi security standard in the Security type section.

What to do to increase security for wifi

If you use WAP2 or WAP3 security standards, you don’t need to worry too much about wifi security because these two security standards are considered the best today.

If you use WAP and WEP security standards, the best way is to upgrade your wifi security standard to WAP2 or WAP3 to ensure safety.
